RECEIVING-SHELF FOR MACHINES.

SPECIFICATION forming part of Letters Patent No. 641,082, dated January9, 1900. Application filed August 29, 1899. Serial No. 728,912. (Nomodel.)

T all whom .it may concern:

Be it known that I, ALLEN CONKLING, a citizen of the United States,residing at Chicago,

' in the county of Cook, State of Illinois, have invented certain newand useful Improvements in Receiving-Shelves for Machines, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention relates to a feeding device adapted to operate inconnection with the delivery elements of any suitable class ofmachinery, and particularly with the rolls present in ironing orpressing machines, for the purpose of receiving and retaining the goodsVupon said device and discharging them therefrom or permitting the goodsto be delivered to a receptacle upon a lower plane than said device.

The invention has for its object to provide a receiving-shelf havingmeans to retain thereon the goods or articles passing through theoperating elements of a machine, said shelf being normally maintained inan inclined position relative to a horizontal plane through the axis ofthe roll. The object of this particular structure is to prevent thecontact of the ends of articles one with another, which is liable tooccur when the shelf is maintained in a horizontal position and in aplane substantially that of the delivery-'point of the rolls. In such acase the ends of articles such as collars and cus upon being deliveredfrom the rolls will strike the end of the preceding article held uponthe shelf and rumple or disfigure the same, In this class of machineryit is not practicable to discharge from the table each article as it isreceived thereon, as there is a continuous delivery of articles from theroll, the same being fed one after another across the longitudinallength of the roll, whereby the article at one end is delivered while anarticle at the opposite end is being introduced. This permits theoperator toiron a large number of articles and maintain a continuousoperation of the machine, and as the articles pass from the deliveryside of the roll they fall upon the retaining-shelf and lie one uponanother, as this shelf is located below the delivery-line of the rolls.

The invention has for an additional object -io provide operating meanswhereby said retaining-shelf may be tilted to deliver the` goodstherefrom to any. suitable receptacle communicating with the front ofthe machine or to permit the goods to fall from the rolls into such areceptacle.

Other objects and advantagesof the invention will hereinafter appear inthe following description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure l represents a vertical cross-section through anironing-machine with the invention applied thereto, 'and Fig. 2 is aplan of the same with parts broken away.

Like letters of reference indicate like parts throughout both gures ofthe drawings.

While it is understood that this feeding device or retaining-shelf maybe applied to any desired class of machine, still for the purpose ofillustration I have shown in the present instance a form ofironing-machine comprising a framework A, supporting a clothed roll Aand a heated roll Athe former being mounted in movable bearings and heldin yielding contact with the heated roll by means of weighted levers A3,pivoted to the frame at each side thereof, lbars A4, in which the roll Ais pivoted, and connecting-links A5 between said levers and bars.

Beneath the roll A any suitableform of receptacle may be supported, suchas a shelf B, having a bottom portion B inclined to ward the front ofthe machine and provided at the rear with bearing-brackets B2, adaptedto pivotally support theretaining-shelf C. This receptacle may besupported by any suitable device-for instance, the supporting lugs orbrackets B3, extending from the opposite sides of the frame A.

The receiving and retaining shelf C is constructed in any desired mannerin order to retain thereon the goods delivered from the rolls, and inthe present instance the same is shown as provided with side andend`walls C', so arranged as to hold the goods when the shelf stands inits normallydnclined position. (Shown in full lines in Fig. l.) Theshelf is further provided with pintles or pivots C2, adapted to rest inthe bearing-brackets B2, and these pivots C2 are located at a pointforward of the center of the shelf, so that the IOO Weight of the shelfnormally holds the same in the position shown in full lines in Fig. land also automatically returns the shelf to this position after it isreleased from the tipping mechanism. As showing a desirable form of suchtipping mechanism, Ihave provided a foot-lever D, provided with a stepD', which lever is pivotally mounted upon a cross-bar AT, carried by theframe A and provided with a rock-arm D2, having at its upper end a slotD3. The lower face of the receptacle B is provided with a bearing-lugB4, carrying a rock-shaft A, One end of this rock-shaft is provided witha crank-arm E, pivotally connected at the slot D3, while the oppositeend of the shaft carries an arm Et, pivotally connected to a link E2,which link, at its upper end, is pivoted to the retainingshelf O forwardof the bearingpivot thereof, as shown at E3. vIt will be seen that adepression of the lever D will tilt or oscillate the retaining-tableinto the position shown by dotted lines in Fig. 1, and the slottedconnection between the oscillating arm D2 and the arm E permits a propermovement thereof to exert a greater leverage from the arm D2 upon thecrank-shaft and connections with the retaining-shelf.

In the operation of the device when the parts are in the position shownby full lines in Fig. 1 the collars or other articles being ironed willfall upon the table in layers one upon another and can be retainedthereon until it is desired to return the same to the operator forfurther ironing or other purposes. When it is desired to thus return thearticles, the table is tilted into the position shown by dotted lines,which discharges the articles into the receptacle B, retaining at thesame time the polished or finished side ofl the goods in the sameposition as when delivered to the shelf. This is important :in caseswhere the opposite side of an article is to be polished by a secondironing operation. When the table or shelf is in the position shown bydotted lines, it will also be obvious that the collars will be delivereddirectly to the receptacle and not received lupon the shelf. For thereasons previously stated it is not desirable to tilt this shelf duringthe continuous delivery of the goods; but it is usual to wait until anumber of articles have been ironed and deposited upon the shelf, whenall of the same may be transferred to the receptacle, and therebyto thefront of the machine.

If the shelf be tilted during the ironing operation, some of the collarsor articles may be damaged, as there is a successive delivery from oneend of the roll to the other.

While the mechanism for tilting the shelf has only been illustrated asapplied at one side of the machine, it is obvious that the same may beduplicated at the opposite side and may also be supported in anysuitable manner to effect the objects of the invention.

It will be further apparent that the device maybe applied to any classof machines where found desirable, and changes may be made in thedetails of construction and configuration of the several parts withoutdeparting from the spirit of the invention as defined by the appendedclaims.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-
